Blue Plate vs Impromptu
Both are Sherwin-Williams colors. These are both blues, so the question isn't which hue to choose — it's where within blue to land. At LRV 23 vs 17, Impromptu will read as the brighter of the two — a 6-point gap that matters most in north-facing or low-light rooms. They share a cool quality — useful to know if you're layering them in the same space. At ΔE 9.8, the difference is perceptible but not dramatic — the two can work harmoniously in the same space. Below you'll find 10 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
Blue Plate vs Impromptu in Real Spaces
10 real rooms side by side. Blue Plate and Impromptu are close enough that the difference can be hard to judge from a chip alone — these photos show how each reads at scale, across different spaces and lighting conditions.
Living Room
Living rooms test a color across a full range of conditions — morning sun, afternoon shade, and evening lamp light all shift how both of these read. Impromptu has the edge in reflectance, which shows as a quiet sense of added space rather than an obvious contrast.
Bedroom
Bedroom walls are often seen under warm artificial light, a context that shifts both colors from how they look on a chip. The brightness difference is modest but present — Impromptu gives the walls a little more lift.
Kitchen
Kitchen lighting tends to be bright and directional, which sharpens contrast and makes undertone differences more apparent. The brightness difference is modest but present — Impromptu gives the walls a little more lift.
Dining Room
Dining room light is typically the warmest in the house, which shifts both colors toward the red end of the spectrum compared to daylight. Impromptu reads slightly lighter here — a subtle but real difference in how open the space feels.
Bathroom
Bathrooms amplify color — the enclosed space and reflective surfaces make what reads subtle elsewhere feel more present here. The brightness difference is modest but present — Impromptu gives the walls a little more lift.
Home Office
In a home office, wall color sits in your peripheral vision for hours at a time, so temperature and undertone matter more than you might expect. The brightness difference is modest but present — Impromptu gives the walls a little more lift.
Mudroom
A mudroom color needs to hold up under the most casual scrutiny: a glance as you're coming and going, often in mixed or artificial light. Impromptu reads slightly lighter here — a subtle but real difference in how open the space feels.
Patio
Patio colors are seen under changing outdoor light throughout the day — morning, midday, and golden hour each reveal different qualities. Impromptu reads slightly lighter here — a subtle but real difference in how open the space feels.
House
At full exterior scale, the difference between these two colors becomes much easier to judge than from a small chip. The brightness difference is modest but present — Impromptu gives the walls a little more lift.
Front Door
Front doors are seen in isolation against the rest of the facade, which makes them a high-stakes surface where even subtle differences matter. Impromptu has the edge in reflectance, which shows as a quiet sense of added space rather than an obvious contrast.

Blue Plate vs Impromptu Simulated Comparison
5 simulated room previews — drag the slider on each to see Blue Plate on one side and Impromptu on the other.
Digital color is approximate. These simulations are generated from the manufacturer's hex values and overlaid on grayscale room photos — your screen's calibration, brightness, and viewing angle all affect how they render. Before committing to either color, test physical samples in your own space under the light you actually live with.
